Mail order tuning is only going to be close, you will most likely still need to get fine tuning done. No tuner is going to be 100% dead on without having the car. If yuor car runs now, check if the tuner wants a scan log to help tune the car.
What do you need tuning for? Bolt-ons or major programming? I know allot of people that are very happy with MadZ, PCM4less and foff67. The thing with mail order is how similar your mods are to others. All of the tuners will probably have files for something like a hotcam, but if you have an odd set-up or want something specail then you will need more then mail order, or at least understand it may take a few times to get things right.
SO IT'S VERY important that the tuner you work with is willing to keep trying if there is any issues and is willing to try multiple times.
When I had just heads+Cam I* used Ed Wright ( Fastchip ) for tuning and it was OK, and was done mail order in that I had to keep sending the chip back and pay the shipping, so there was extra cost to me.
For my stroker supercharger tune I needed allot more special tuning One tuner couldn't figure it out, but PCMforless said it was no problem! I'm running the PCMforless tune done by Alvin ( 93LT1 have chips/ Speed Density, 94+ don't so Brian would tune then). . But I consider it more then just a mailorder. Alvin sent me the chip with a basic tune, I then drove / scanned the car, sent him the scan files and told how how the car felt, and he sent me back new files to update the chip. ( I purchased the software and hardware to burn chips). Took Alvin two tries to get everything dead on. Car runs perfect and scans show the fuel/timing are dead on, but I still want more WOT tuning, and will send Alvin a file when I get the car on the dyno. I also want to have Alvin do dyno tuning real time, next time he's in PA to make sure the tune is 100% before I remove the FMU.
